Tratamiento de aguas residuales mediante tanques sépticos, con su estudio de impacto ambiental, en la comuna Manchacaso de la parroquia Canchagua cantón Saquisilí provincia de Cotopaxi

Abstract

This project contains the design of a septic tank, with its respective environmental impact study, conducted in a home belonging to the parish of Canchagua in the canton of Saquisili in the province of Cotopaxi, using the technical standards for the design, specifications, and their due adjustments. For the development of the work, it was decided to perform 3 sampling on different days, so that the results of the analysis present fewer errors; the NTE-INEM 1108, (2014), was used for sampling; we proceed to perform the physical, chemical and bacteriological analyses in order to know the water quality and subsequently compare with the maximum permissible limits established in the Ministerial Agreement No.097- a, (2015). Once the data were obtained, the design calculations were made to implement the septic tank, in this case the grease trap, the screening system, the primary settler and the chlorination tank were designed in that way to reuse the water is irrigation systems in agriculture. The SEWER CAD program and the AUTOCAD program plans are necessary for the parish government to decide to implement the project, as well as the economic, technical, and social study to ensure the feasibility and sustainability of the project. For the environmental impact study, a matrix of importance was used regarding the impacts that the project could generate, and the Environmental Management Plan is presented for the construction, operation and maintenance, and closure and abandonment phases.
